324.0. "PQL_M* sysgen parameters set too low in DECW$CHECK_PAR" by CSC32::JJONES () Sat Mar 04 1989 22:08

    Dear All:
    
    In DECW$CHECK_PARAMS.COM it checks to see if, among others,
    the SYSGEN parameters PQL_MWSQUOTA & PQL_MWSDEFAULT are
    equal to 60. If higher or lower, it suggests changing them to
    60. 
    
    Now, a couple of things:
    
    	1) I thought the PQL_M* parameters were not to be modified
    	   and to be just used as minimum settings below which
    	   the PQL_D* parameters should not be set.
    
    	2) I work at CSC, and today had a customer who modified,
    	   at DECW request, these parameters to 60 and rebooted.
    	   DECW would not come up and produced LKWSETFUL errors.
    	   Which is not unexpected considering what I understand
    	   about these Sysgen Parameters. We changed the PQL_M* 
    	   parameters back to default and all worked well except
           for CHECK_PARAMS yelling about them.
    

    Should this be happening? If so, Why?
    Do I have the right definition of the Sysgen Parameters?
    
    
    Hmmmmmm,
    jjjones

    A little more about .0
    
    The customer is on a VSII/GPX.
    
    I have a VS3100 and my PQL_M* parameters are set to what 
    DECW$CHECK_PARAMS.COM wants to see them as and I have no
    problem.

    Has your customer changed VIRTUALPAGECNT higher than what AUTOGEN
    would calculate it to? I had this same
    problem on my 16MB VS3200. I had upped VIRTUALPAGECNT to 200000
    to be able to analyze large crashdumps. With  that high VIRTUALPAGECNT
    i a) either got LKWSETFUL at boot time or b) had to change PQL_MWSQUOTA
    to a higher value and then CHECK_PARAMS complained.
    
    After i lowered VIRTUALPAGECNT to 100000 LKWSETFUL problem went away.

re: .0, .2

We have had a similar problem with a 3500 with 32meg of memory.

We eventually modified DECW$CHECK_PARAMS.COM to check that these
parameters were atleast 60 but greater ok.

With machines with larger amounts of memory and/or large virtual needs, these
parameters must be greater than 60 or you will get a lock working set full
problem.  We have filed the problem in this notes file (?? or some other
permutation of this notes file) and qar'ed it, but the problem still seems to
get shipped. 

Guess they don't expect some decent sized work stations out there...

PQL Minimum SYSGEN Parameters Used For Interactive Logins


COPYRIGHT (c) 1988 by Digital Equipment Corporation.

TITLE: PQL Minimum SYSGEN parameters used for interactive logins.

PRODUCT: VMS, Version 4.n
 
DATE: January 1988

SOURCE: Customer Support Center/Colorado Springs

\       by G. House of VMS/C

INFORMATION:
 
Users get higher values than those specified for process quotas and/or
working set sizes in their UAF records. 

When a login is performed using LOGINOUT, one would expect that all
the process quotas would be taken from the values defined in the UAF
record for the user.  This is not the case.  The PQL_Mxxx SYSGEN
parameters are also utilized. 


ANALYSIS:
 
The PQL parameters define the default (PQL_Dxxx) and minimum
(PQL_Mxxx) values to be used for the associated process quotas.  The
default quotas are used for detached processes which do not execute
LOGINOUT to acquire the quota values from SYSUAF.  The minimum 
parameters are enforced for all processes on the system.


The following values are affected:

        WSQUOTA, Working set quota
        WSEXTENT, Working set extent
        WSDEFAULT, Working set default
        PGFLQUOTA, Page file quota
        BIOLM, Buffered I/O limit
        DIOLM, Direct I/O limit
        BYTLM, Byte count limit
        PRCLM, Subprocess quota
        FILLM, Open file quota
        ASTLM, AST quota
        TQELM, Timer queue quota
        CPULM, CPU time limit
        ENQLM, Enqueue (lock) quota
        JTQUOTA, Job logical name table quota
